Helping Kids Focus at School

As kids return to school and begin to settle in to their new routines, some parents and teachers will begin to notice some challenges with focus. Perhaps there was a suspicion at the end of the previous years, other times, it may be a new concern. My child can't sit still. The teacher says they're distracted. Homework takes three hours and half of it is meltdown. Focus is one of the most common things families bring to me once school is underway, and I understand why, because a child who can't focus struggles everywhere at once — in the classroom, with friends, and in their own frustration with themselves. So let me start with the most important thing I can tell you: focus is not a character trait or personality flaw. Your child is often not doing it on purpose.  In many ways it is a state of the nervous system, and a nervous system that needs to and can be supported.

First Let’s Talk about Focus

When we ask a child to focus, we are asking a great deal of the brain. We are asking it to filter out distraction, hold information in their minds, manage impulses, and stay regulated enough to do all of that at once. This is executive function, and it develops gradually all through childhood — some kids faster, some slower, and all of them worse when they are tired, hungry, overstimulated, or stressed. That last part matters more than almost anything. A dysregulated nervous system cannot focus, no matter how bright or motivated the child is. So most of what actually helps is not about trying harder. It is about building the conditions that let a child's attention work for them instead of against them.

A Calm Body is a Happy Body 

A child who is anxious or over stimulated  is running on a nervous system stuck in high gear. No one, including you, can think clearly from there. The good news is that we can teach kids simple ways to shift out of it, and these work right at their desk, often without anyone noticing.

Breathe out longer than you breathe in. A slow breath out is the single fastest way to tell the nervous system it is safe to settle. Teach your child to breathe in for a count of four and out for a count of six. A few rounds before a test or a hard assignment genuinely changes their physiology.

Give the body something to do. Many kids focus better when their hands or body have a small outlet — a fidget, a piece of gum, a water bottle to sip, feet pressed flat into the floor. This is not misbehavior. For a lot of children, a little movement is what frees the mind to attend.

Use grounding when things get big. When a child feels overwhelmed, having them silently name five things they can see, four they can hear, and three they can touch pulls the brain out of the spin and back into the room. It is simple, and they can do it anywhere.

Feed Their Brains! 

What a child eats shows up directly in how they attend, and this is an area where families have real power. The two things I tell every family (and honestly this is regardless of whether their child seems to be having challenges with focus): 

Watch the artificial dyes. This one has moved from fringe to mainstream. A large California state review concluded that synthetic food dyes are associated with inattention, hyperactivity, and restlessness in some children, both with and without a diagnosis — enough that California is removing six common dyes from foods served in public schools. Europe has been ahead of the game for years. Since 2010, any product sold in the European Union that contains one of six dyes tied to hyperactivity (the “Southampton Six,” including Red 40, Yellow 5, and Yellow 6) has had to carry a warning label reading that it “may have an adverse effect on activity and attention in children.” Rather than print that on the box, most manufacturers simply reformulated with natural colors like beet, turmeric, and paprika, which is why the same candy or cereal often looks different abroad. Not every child is sensitive, but many are, and the dyes offer nothing of value. Read labels, and when focus is a struggle, cutting Red 40, Yellow 5, Yellow 6 is an excellent first step. 

Aim for an anti-inflammatory plate. The steadiest way to feed focus is a Mediterranean-style pattern: vegetables and fruit, whole grains, olive oil, fish, and nuts, with less processed food and added sugar. You have heard me say this before: less than 25g of sugar per day is the goal.  This lowers the low-grade inflammation that works against a developing brain, and it keeps blood sugar steady, which spares kids the spikes and crashes that wreck attention by mid-morning. Protein at breakfast is the highest-leverage meal of the day for a child who needs to focus.

A Word on Saffron

Families often ask me whether anything besides medication that supports attention, and saffron is the one with the most compelling evidence behind it. In several randomized, double-blind trials in children with ADHD, saffron extract performed comparably to methylphenidate, a standard stimulant medication, over six to eight weeks, with hyperactivity the area where it stood out most. Its active compounds appear to influence the same dopamine, serotonin, and noradrenaline pathways that attention depends on, alongside anti-inflammatory and antioxidant effects. I find this genuinely promising. I also want to be honest that these studies are still small and short, and saffron is not a replacement for a proper evaluation or for medication when a child needs it. If your child struggles with attention, this is a real conversation to have with us — not a supplement to start on your own.

The Foundation: Movement and Sleep

None of the above works well on a body that is depleted, and two inputs do more for focus than any strategy I can teach.

Move the body every day. Physical activity is one of the most reliable focus interventions we have. Exercise raises the very neurotransmitters that attention runs on, and even short bursts help. A child who moves before school, or who gets real recess and outdoor time, comes back to the desk better able to focus. Movement is not the reward for finishing the work — it is part of what makes the work possible.

Get them outside, often. The countries with the best outcomes have understood this for a long time. In Finland, where students consistently score above the international average, comprehensive-school classes run just 45 minutes and are followed by a 15-minute outdoor break — outside after every single lesson, rain or shine. Their kids spend fewer hours at their desks than ours do and still come out ahead, and frequent outdoor breaks are a big part of why. Attention is not endless; it needs to be reset, and fresh air and movement reset it better than pushing straight through. You can borrow the principle at home: build outdoor time into the after-school hours before homework rather than saving it for after, and let the school day's mental fatigue clear before you ask for more focus.

Protect sleep fiercely. A tired brain cannot focus. You know this. You have lived this yourself. Sleep is when the brain consolidates learning and resets attention for the next day, and a child running short on sleep will look just like a child with an attention problem. Steady bedtimes, a calm wind-down, and screens out of the bedroom are not separate from focus. This is mission critical. 

When to Reach Out

Sometimes a family and child do everything right and focus is still a daily battle. This is worth paying attention to. If your child's difficulty is persistent, showing up across settings, and getting in the way of learning or friendships, please come talk with us. Struggling to focus is not a failure of effort or character, and no child should be left to struggle and figure out how to just survive a school day. The goal is a child who can settle, attend, and feel capable in their own mind — and there is a great deal we can do, together, to help them get there.
